Intensity Physical Activity (intensity + physical_activity)
Selected AbstractsHealth-promoting physical activity of adults with mental retardationDEVELOPMENTAL DISABILITIES RESEARCH REVIEW, Issue 1 2006Heidi I. Stanish Abstract This literature review describes the physical activity behavior of adults with mental retardation consistent with the U.S. Surgeon General's recommendation of 30 minutes of moderate intensity physical activity on 5 or more days per week. The proportion of participants achieving this criterion ranges from 17.5 to 33%. These data are likely to be generous estimates of activity as individuals included in physical activity studies to date have been relatively young and healthy volunteers with mild to moderate limitations. Major sources of physical activity were walking and cycling for transport, chores and work, dancing, and Special Olympics. There is a pressing need to conduct studies using appropriately powered representative samples and to validate measures that assess physical activity less directly; including methodologies in which proxy respondents are used. Accurate information about existing patterns of behavior will enhance the development of effective strategies to promote physical activity among persons with mental retardation.

Berntsen Background:, Evidence regarding habitual physical activity levels and aerobic fitness of asthmatic compared to nonasthmatic children and adolescents is contradictory, and it is unclear if low physical activity levels can contribute to asthma development. The present study therefore aimed to determine whether adolescents with asthma have reduced physical activity levels and aerobic fitness, or increased energy intake and body fat compared to controls. Methods:, From the environment and childhood asthma study in Oslo, 174 (13- to 14-year old) adolescents, 95 (66 boys) with and 79 (41 boys) without asthma performed maximal running on a treadmill with oxygen consumption measurement (aerobic fitness) and had the sum of four skinfolds and waist circumference recorded (body fat), followed by wearing an activity monitor and registering diet for four consecutive days. Asthma was defined by at least two of the following three criteria fulfilled: (1) dyspnoea, chest tightness and/or wheezing; (2) a doctor's diagnosis of asthma; (3) use of asthma medication. Participants with asthma used their regular medications. Results:, Neither aerobic fitness, total energy expenditure nor hours in moderate to very vigorous intensity physical activity during week and weekend differed between adolescents with and without asthma. Energy intake and body fat was similar in both groups. Conclusions:, Total energy expenditure, aerobic fitness and hours in moderate to very vigorous intensity physical activity were not reduced and energy intake and body fat measured with skinfolds not increased among Norwegian adolescents with asthma. [source] The immediate effect of physical activity on standing balance in healthy and balance-impaired older peopleAUSTRALASIAN JOURNAL ON AGEING, Issue 2 2009Thorlene Egerton Objective:,To determine if standing balance was affected by moderate levels of physical activity in healthy young, healthy older and balance-impaired older adults. Methods:,Thirty-one healthy young, 33 healthy older and 22 balance-impaired older adults took part. Centre of pressure (COP) motion was measured before and immediately after participants undertook 14 minutes of self-paced, moderate intensity physical activity. Results:,All groups responded in a similar manner. Following the physical activity circuit, mediolateral COP displacement and standard deviation of mediolateral COP position increased by 5% and 17%, respectively. Anteroposterior COP displacement and COP standard deviation, and total COP displacement, did not change. All changes were small compared with the magnitude of the group differences. Conclusions:,A small increase in fall risk may exist immediately following physical activity and older people may need to exercise caution following moderate intensity bouts of physical activity to prevent falling. [source] Objectively measured habitual physical activity in a highly obesogenic environmentCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 3 2009S. A. McLure Abstract Background While the prevalence of overweight and obesity among children continues to grow nationally, prevalence in the North-East of England is among the highest in the UK. The objective of this study was to investigate the habitual physical activity levels in a particularly obesogenic environment in the North-East of England. Methods Eight primary schools were selected using a stratified random sampling frame ranking average deprivation levels. Participating children (n = 246, mean age 10 years) wore an accelerometer (Actigraph, GT-256) over five consecutive days (weekend plus three weekdays). Total daily moderate-to-vigorous intensity physical activity was calculated using thresholds by Puyau and colleagues. Results Only 7% (17/246) of children were sufficiently active. Boys were more physically active than girls (766 ± 268 vs. 641 ± 202 counts/min, 95% CI for the difference 63,186 cpm.). Total physical activity was not influenced significantly by deprivation levels or weight status, and there were no significant differences in physical activity between school or weekend days. Conclusions The North-East of England is a recognized ,hot spot' for paediatric obesity and the present study shows that low levels of habitual physical activity are typical. Choice of accelerometry threshold affects both the apparent amount of physical activity and the ability to detect groups with particularly low levels of physical activity. [source] Active commuting to and from school and BMI in elementary school children , preliminary dataCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 3 2005K. A. Heelan Abstract Background, United States National Health Objectives include increasing the proportion of trips made by walking to and from school for children who live within 1.6 km to 50%. The purpose of this objective is to increase the level of physical activity among children. However, the impact of walking, bicycling or skating (active commuting) to and from school on the prevalence of overweight is unknown. Methods, Body mass index (BMI) was measured for 320 children (age 10.2 ± 0.7 years) in September. Over 5 months, an active commuting index (SI) and daily physical activity were estimated via questionnaire. In April, BMI and body fat were measured. Results, A significant positive association was found between April BMI and SI adjusting for September BMI (partial r = 0.03, P < 0.05). Positive associations were found between SI and physical activity before school (r = 0.17, P < 0.05) and daily moderate intensity physical activity (r = 0.13, P < 0.05). There were no significant association between SI and BF (P > 0.05). Conclusions, This preliminary data suggests that active commuting does not appear to provide sufficient amounts of physical activity to attenuate BMI; however, it may contribute to the attainment of physical activity recommendations. Future research is needed to objectively measure the impact of active commuting on the prevalence of overweight. [source] |
